q Camera
You can select camera 0 or 1 (if 1 or 2 cameras were created) and display the camera’s view in the Viewer window. This will also be the view used for still image rendering and animation.
q Shadows
Check this box to compute and display shadows.
By default, Amapi 3D will smooth between two facets when rendering. The smoothing angle defines the angle below which two adjacent facets will be smoothed. You can deselect this smoothing option, or modify the smoothing angle value (0°=no smoothing; 180°=all the vertices will be smoothed).
This feature gets rid of the “jaggies” surrounding shaded shapes.
Select the level of anti-aliasing you want (from 0 to 3)
The use of anti-aliasing increases the rendering time.
q Background color
Specifies the background color to be used during rendering.
q Background image
Check this box to display a background image when rendering the scene. The image is not visible when modeling, but is displayed in the preview window of the Material Editor and in the rendered image.
The rendered scene is displayed scan-line by scan-line, i.e., row of pixels by row of pixels. By default, 20 rows are processed at a time. If you are short on RAM, specify 3 or 4 rows instead.
